JOHN M. BOSGARIDIN, or CANAAN, ooivnrac'rrou'r I DEVICE FOR VRAISINGVLSUBMERGED, oBJnors Application filed .Tune 20,

This invention relates to improvements in devices for raising submerged objects such as ships.

One of the objects of this invention isto provide an eliicient apparatus for grappling and raising vessels which have been submerged at sea and which is simple of construction and easily operated and controlled from a salvaging ship or other center of operation.

A purpose of this invention is to provide a device for raising submerged objects, the device comprising a hollow receptacle or a plurality of them, adapted to be supplied with suflicient liquid to submerge it in the proximity of the object to be raised, and having adjustably suspended from the hollow recepta-, cle a plurality of grappling cables, operable means being attached to the hollow'receptacle for bringing the grappling cables into desired position in contact with the object to be raised. I i

A further object of this invention is to provide a device for raising sunken ships and the d like, having means operable from a salvaging ship or other centerof operation for firmly Other objects of this invention will appear from the following detailed descriptionof the device and as disclosedin the two sheets of drawings which are herewith made a part of this application.

In the drawings the device for raising submerged objects in assembled relationship with a salvaging vessel.

Figure Trepresents a perspective view of the cable belt memberadapted to the purpose of supporting the weights in adjustable relationship to the hollow receptacle] In thedevice for raising submergedob a jects, according to this invention, it is preferred that numeral ldesignates a salvaging ship or other centerof operation'adapted for a hollow. receptacle 2, which may be made'off the purpose of cooperating in adjusting the cast iron or other suitable material, in proper position'relative to a submergedobject such T as a sunken ship 3; l r s I In the process of raising the ship 3, a plurality of the hollowreceptacles 2 may be used the purpose of thisi application the following escription will cover but one of the devices designated by the numeral 2.

figuration, but preferably oval inform, as disclosed in the drawingsi The construction of this container '2 must be along the lines ,of maximum strength in order towithsta'nd pressures existing in deep sea the tremendous workup p The airv capacity of the container 2 should be sufiicient for theraising of the object. Figure 1 illustrates a perspective view of Integrally fastened or otherwise to the pe-r "if it is considered necessary. r However, for i The generalshapef of the container-orhollow receptacle 2 may be of any desirable con- I ripheryof the receptacle 2is a bandmember 4, made of cast iron or other suitable material and adapted to have integrally formed therewith or securely fastened thereto a pluralf ity of lug members 5,having openings therein for loosely receiving cable portions fi,

which are adapted to extend downwardly from the receptacle a suitable distance, and

having attached at theends thereof a 'plu rality of grappling members 7 which maybe a during the raisingthereof.

In normal position the cables 6 and grappling members 7 will hang suspended from the container 2, and intermediate between the points of suspension and the grappling members 7, along the cable elements 6 are 1 adapted to be located a plurality of clamping 3079 closed innormal iuplifted position previous to 7 cablelQ,havingiupwardly extending endpon tions and i217 for: operably holding dogele- 'aments22 and23, extends throughasuitable tting 24, upwardly to thesalvaging ship 1, where it may be. operated by meansof aiwindlilSSpLOll other; suitable device.

the cap, 26., .is providedxhaving anFopenin-g therein :for receiving .a. chain or cable mem-.

berz29. which extends from the. top tofzthe receptaclee2 to theiisalvagi-ng ship.l1, where it may be operably connected with a windlass. The hollowgreceptacle 2.is p.rovided.with a pluralityofeguidelines 30 and .31, which prefb y ar at aohedto the. band member-4' at one, end .1 and extend gintmthe salvagingship 1, where they are, operated by -hand ,or other; wis ,e,as maybe desired, forthe,purposeof =1 guiding the receptacle 2 and .holdiugitfirml in position...

The receptacle -2 in this inventionmay'be supplied with a suitable amount of liquid and, air in the usual'manner, such as liquidand 2 to-proper pumps located in the salx' aging ship. Anair line 32 extending from a suit able fitting 33 leads upwardintothe salvaging ship. .1; as clearly disclosed in Figure-1,

5s and a pipe line 34 is shown ,extendingafrom the receptacle 2 upward into the ship 1. The lowerportion of the pipe line 34 may extend inwardly of the receptacle 2 a suflicient dis tance for assuring the complete pumping of the liquid therefrom, if desired, by means of a pump located in the salvaging ship 1.

Obviously, the locationoi the air and liquidpipe lines, so far as this invention is concerned, has no appreciable effect upon the spirit thereof. It may. be desirable under some circumstances to have the container filledwith approximately two-thirds water and one-third compressed air, the proportionsof which are adapted to be regulated from the salvaging ship 1.

In operation thisinvention provides an eifi'cientmeans for raising a'submergedob ject such as a vessel which has been sunk in deep-waters, The container 2 is supplied with a suitableamount of liquid and air, and positioned at a desiredpoint'above the submerged object, as clearly shownin Figure 1, after which the cable 19 is operated from the salvaging ship 1, andthe weights 11 and12 are allowed to move downward thereby forcingt'the grappling members? into close contact withrthe submerged object 3 by means ofthe belt cable 10. The proportions ot'airand liquid within the-container 2 may then beeasily regulated, for-instance, the liquid maybe entirely removed by pumping, and compressed airsubstituted, or certain proportions ofair and liquid admitted in the container, depending upon the requirements of-the situation.

In case the submergedobject is firmly-held in the mud, or otherwise, it may be found desirable to haul in-onthe chain 29 by proceeding ahead with the salvaging ship 1, which will very likely tend to lessen the hold of'the submerged object in the mud:

It. will be understoodthat many changesand modifications may be-madein the'fornr of embodiment of the invention within-the scopeof the followingclaimswithout departing from the spiritof the invention.

What Iiclaim is:

1. In adev-ice. of the character described, a container, a band element connected thereto, a plurality of cables supported by the. band member, grappling members attached to. the cables, means adjustably connected with the container; constricting the cables and grapplmg members.

2, In a; device of] the character described, a container, aband element connected thereto, a plurality. of cables supported by. the band member, grappling members attached to the cables, means adjustably connected with the container constricting the cables and grappling members, guiding means extending from the container for locatingthe container in position.

3;: In a device of the character described,

a container ,a .band element connected thereto, a plurality of cables supported by the band member, grappling members attached to the cables, means adjustably connected with the container constricting the cables and grappling members, guiding means extending from the container for locating the container in position, hauling means extending from the container.

4:. In a device of the character described,

a container, a band element connected thereto, a plurality of cables supported by the band member, grappling members attached to the cables, means adjustably connected With the container constricting the cables and grappling members, guiding means extending from the container for locating the container in position, hauling means extending from the container, liquid and air supply means extendinginto the container.

5. In a device of the character described,

a container, a band element connected thereto, a plurality of cables supported by the band member, grappling members attached to the cables, a cable belt operably supported by the container, a plurality of Weights fastened thereto, means for allowing the weights to drop thereby forcing the cable belt into constricted relationship with the cables and' the grappling members.

In testimony whereof I affix my signature.
